Sir Isac Newton's Laws of Physics
Here in the land of physics we are a big fan of Sir Issac Newton and because of that I hope that if you are on a physics web site you know Newton’s laws, but just in-case you forgot I’m going to list them below.
N1L- An object at rest or in motion at a constant velocity tends to stay at rest or in motion at a constant velocity.
N2L- F=ma or Force=Mass x acceleration due to gravity
N3L- For every force there is an equal and opposite reaction force.
N1L- An object at rest or in motion at a constant velocity tends to stay at rest or in motion at a constant velocity.
N2L- F=ma or Force=Mass x acceleration due to gravity
N3L- For every force there is an equal and opposite reaction force.
Newton's first law
N1L is extra fun for speed skater since we are on (kind of) frictionless ice. Since we have little to no force of friction to slow us down once we have started moving stopping is not something we can do quickly. Since speed skaters get into motion the best way for us to stop is by hitting the boards (don’t worry there are mats). This allows us to counter N1L because walls don’t move which means, unless something has gone horribly wrong, we transfer our energy into the wall and are able to stop. N3L also means that the acceleration we

Newton's third law
N3L is our lord and master seeing as without it speed skating (and pretty much every other sport or movement) would not be possible. Newton’s Third law means that when a speed skater does their push to the side they are able to go forward. The force applied to the blade when pushing to the left would be applied to the left meaning the reaction force would push you with the same force right. Speed skaters however are masters of the hip scoop which allows them to redirect this force into a forward motion.

Story Time/ Real Life Application
So on the topic of Newton's laws I have a story for you. At a race meet earlier this year, I was on about my second lap and then I face planted on the straight (something that doesn't happen often) and then I got a real life lesson on Newtons laws. From the fall I slid through the middle of the track back through the corner and into the mats (I attached a picture below that kinda gives an idea of what happen). The first Newton's law I noticed was N1L I was in motion and then I stayed in motion despite the fact I was trying to stop myself from crossing the track again and getting run over. I felt N3L after I finished the race. All the fore I hit the ice with hit me back. The reaction force felt a lot like doing a belly flop....
